Your handwriting stays on your iPad.

Persian Ink does not send your handwriting, recognition results or inserted text to a server. We do not keep a typing history, sell typing data or use your writing to train a model. No account is required for local use.

After text is inserted into Notes or another app, that app controls its storage, backup and sharing. Persian Ink does not acquire access to that app’s note library or handwritten pages.

Ink in the keyboard is temporary. It clears after insertion or deliberate discard and may be lost when the keyboard closes. Practice text stays on its practice screen; copy anything you want to retain before leaving.

The recognizer stores downloaded model files on your iPad. Model downloads and related SDK session files may use a container shared only between Persian Ink and its own keyboard. Handwriting and typed text are not stored in that shared area.

Google ML Kit supplies the recognizer. Google states that input data and recognition output are processed on device and are not sent to Google. When network access is available, the SDK may contact Google for models, updates and operational metrics.

These metrics can include device/app information, a per-installation identifier, configured language, feature events, error codes and processing timing. The SDK’s privacy manifests declare the relevant data categories. This is not a claim that the app collects no data.

Keep Allow Full Access off for normal offline use after model setup. Temporary setup access permits the keyboard to use the network for model downloads and allows the SDK’s operational network activity. Persian Ink does not use that permission to upload handwriting or typed text.

The containing app has ordinary app network access independently of the keyboard permission. Turning off keyboard Full Access is not a claim that the entire app or every embedded SDK is incapable of network activity.

Password fields, some other protected fields and apps that disable third-party keyboards use Apple’s keyboard.

Apple handles App Store purchases under its own policies; we do not receive payment-card details. Persian Ink has no subscription or in-app purchases.

If you choose to email support, the email and information you provide are used to address your request. The app does not automatically send us support content or diagnostic bundles. Do not include passwords or private notes.
